MEANS FOR OONNEOTINGy MOTORS TO MACHINES.

SPECIFICATION' forming partof Letters Patent No. 712,659, dated November 4, 1902.

Application tiled April 28,

.To @ZZ whom it may con/cern: i

Be it known that we, CHARLES E. DONNA- `TIN and CLARENCE V. GREEN'AMYER, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Means for Connecting Motors to Machines, of which the following is a specication. i

Our invention relates to mechanism where-I lo by a motor may be connected and adjusted to a machine, such as lathe or other machine tool, and has for its objects to dispense with belts, counter-shafts, and belt -shifters by furnishing means whereby the motor may be directly connected to the machine and movable bodily with respect thereto to give various rates of speed to the machine withouty changing the speed of rotation of the motor, and also affording means'to change the direczo tion of rotation of the machine.

Another object is to provide means where! by the connection between the motor and the machine may be frictional and to provide; means for securing the requisite amount ofV p friction-bearings, comprising a series of balls friction.

Another object is to provide ja means fori supporting that portion of the machine which receives the frictional contact.

Other objects-such as simplicity of con- 3o struction, ease of adjustment, and reliability of operation-are attained, which willbe set forth in the following description.

Figure I is a view showing our invention4 applied to a lathe,ionly a portion of. the lathe being shown.

tain details of the driving mechanism of the lathe. Fig. III is a detail showing a mechanism for counteracting the effect of strains applied to certain moving portions of the 4o lathe-gearing. Fig. IV is a plan View of the adjusting mechanism, partially shown in seotion. Fig. `V is asectional detail of portions ofthe mechanism shown in Fig. III.

The frame 2 is provided with grooved ways Fig. II is a view showing cer' ieoz. serai No. 105,106. (No mode.)

AAin adjustable cups 24.

5. Mounted to slide along the Aways 5 is a movable frame 6. The movable frame 6 is provided with V-rails, forming ways 7, which lie at right angles to the line of movement of the movable frame 2. A motor 8 may be mounted upon the ways 7. l The motor 8 may be adjustably held on the ways 7 by screws 9, which pass through lugs 10, projecting from the movable frame.

11 is a screw, which may be swiveled at 12 to the stationary frame 2.

13 is a hand-wheel for the screw 11.

14 is a nut carried by the movable frame 6 and in engagement with the screw l1.

l5 is a friction-wheel carried by the shaft of the motor 8, and 16 is an arm for supporting the shaft and friction-wheel.

17 is a friction-disk revolubly mounted on a bracket 1S and connected to the lathe-head by gears 19 and 2U. The disk acts as a iiywheel to the machine and helps to maintain an even rate of speed in the machine. The

Vdisk 17 carries a steelrim 21.

22 is an antifriction-roll mounted on antifers or balls were placedagainst each other is avoided. This method of construction also secures a bearing capable of relieving the large amount of friction which results from the pressure between the roll 22 and the disk 17 and from the high speed of the roll 22.

The balls 23 and rollers 23ai are supported The cups 24. are screwed to a yoke 25.

2G represents locking-nuts.

The'yoke 25 has a threaded shank 27 ,which passes loosely through the bracket 18. 9o

28 represents threaded hand-nuts for hold. ing the shank and yoke in position.

The yoke 25 is positioned so that the roll 22 may bear against the steel .rim 21.

The motor may beadj usted upon the ways 7 bymeans of the screws 9, sothat the friction-wheel 15 may bear with any desired pressure against the disk 17. When the motor runs, the disk 17 is rotated through the medium of the Wheel 15, and by turning the screw 11 the frame 6 may bemoved on the Ways 5 to carry the motor and its frictionwheel 15 along the face of the disk 17 to secure the proper positioning of the wheel 15 on the disk 17 to secure the desired speed or to reverse the movement of the disk. Fig. I shows in full lines the motor and wheel 15 in position to rotate the disk 17 at a relatively low speed, while the dotted lines indicate a position the motor may have to impart a relatively higher speed to the disk 17. The roll 22 revolves against the steel rim 2l and holds the disk 17 true toits plane of movement and opposes the pressure of the wheel 15 against the opposite face of the disk, which tends to throw the disk out of its true line of movement away from wheel 15 and losing the required friction.

While this invention has been shown and described as connected to a lathe, it is evident that it may be applied to other forms of machines as well. Likewise other motors than electric may be employed. The friction-disk 17 could be carried directly on the shaft of the machine or it could be connected to the machine by other` gearing. Obviously many other changes may be made in the particular construction herein shown and described Without departing from the spirit of our invention as defined in the claims.
